Question

我试图在所有类中定义切入点，或者在Spring中导入的库中至少定义一个类。但是，当我运行应用程序时，我得到了

[tomcat:launch] SEVERE: Servlet  threw load() exception
[tomcat:launch] java.lang.IllegalArgumentException: warning no match for this type name: com.example.package [Xlint:invalidAbsoluteTypeName]

错误消息提供了一个很好的提示：

no match for this type name:
com.example.package [Xlint:invalidAbsoluteTypeName]

您似乎在切入点中指定了一个纯粹的包名称作为类型名称。可能你想写这样的东西：

com.example.package.MyClass针对特定班级
com.example.package.*适用于包中的所有类
com.example.package..*

Spring AOP：可以在导入的类或接口中定义切入点，以及如何？
